ATTORNEY wlTNEssEs ZW J//o Patented' Aug. 1s, 19151 PATENT OFFICE LOUIS E, comme, or NAPOLEON, OHIO SAFETY-RAZOR Application filed' January 15,` 1930. Serial No. 420,930.

VThisinvention relates to a safety razor. The principal `object of the invention is the provision `of a safety razor embodying improved features'of construction to the end u that either a flexible or nonilexible blade may be used', and also so that the cutting edges of fthe blade may be disposed at different distances from theguard tovsuit the different requirements'of the user. l The nature of the invention and its distinguishing features and advantages will ap- `pear when th-e following specification is read 1n connection .with the accompanying drawn l ings, in which 16 Figure 1 is a top view of a safety razor constructed in accordance with the invention .Figure 2 is a section taken on the line 2 -2 of Figure 1; l

Figure 3 is a view similar to Figure 2 but showing the lower clamping member in a reversed position in order to obtain a changed adjustment of the cutting edges of the blade with respectto the lower clamping member, which constitutes the guard for the blade; Figure 4 is a view of the under side of the to clamping member; Q

, *igure 5 is a`plan view of a flexible blade used with therazor; v

Figure G is4 a view looking at the top side 39 of the lower clamping member or guard;

Figure 7 is a viewlooking at the undef' side of a lower clamping member or guard;

Figure 8 is a plan view of a uch-flexible blade adapted to be used with the razor.

Referring more particularly tothe drawings, it will be apparent that the razor of the present invention comprises anupper clamping member 10, a-lowerelamping member 11 which cofoperatesV with the clamping member o 10, a blade 12 which is held in place between the clamping members 10 and 11, and a handle 13 adapted to be engaged with \portions of the clamping members 10 and 11 to hold them in clamping engagement with the blade razor consist of the following features. The

` upper clamping member 10 is of quadrangular shape and is concavo-convex in cross see 5 tion. Arranged centrally of the clamping l a recess 20 therein and a threaded bore 21 4mg memberlO and the convex face of the More specificially stated, the parts of the member 10 on the under concave face thereof and formed integral therewith is a stud or peg 14. This stud or peg 14 is angular in cross section, the same being square in the present instance with slightly rounded cor- 11ers. The stud or peg 14 has a reduced cross sectional round end or extremity 15 which is threaded.` The clamping member 11 is also quadrangular in shape vand is somewhat larger in area than the clamping member 10. The clamping member 11 is coneavo-convex in cross section,` and is provided with guard teeth -16 on the marginal edges thereof.` It will therefore be understood that the clamping member 11 serves as a guard forthe blade 05 12. The clamping member 11 has -arran ed centrally thereof on the upper concave ace a rest or boss 17, of angular formation inplan, the same beingsquare in the present instance. f The clamping member 11 has a re- 7o cess 18 in the lower convex face thereof.

The clamping member 11 also has a central hole or opening 19, of a shape to conform to .y the cross sectional shape of the stud or peg v14. T he handle 13 is made of two parts in the 75 present instance, and the upper end thereof is of such formation as to con-form to the shape of the recess 18 in the clamping member# 11. The upper end of the handle 13 also has disposed axially thereof.

It is to be understood that use may be made of a flexible blade or a non-flexible blade. In the present instance the blade 12 shown 1sl a flexible one. This blade has narrow notches or slits 22 extending diagonally in order to give 1o the blade the desired flexibility. The

blade has a hole or opening 23 centrally thereof of a formation to conform to the shape of and to receive the stud or peg 14.

From the foregoing it 4will be apparent that the clamping members 10 and 11 may be brought together with .the blade 12-dis posed between the concave face of the clampclarnpng memberll. The stud 14 projects f through the holes 19 and 23, respectively, 1n

'the clamping member 1:1 and the blade-'12.`

The handle 13 is applied to the clamping members 10 and 11 to maintain them in 100 clamping engagement with the blade 12, and is accomplished by threading the end of lthe handle having the bore 21 on the threaded end or extremity 15 of the stud 14, as shown in Figure 2. The blade l2 will be exed so that the cutting edges thereof will be dis! posed relativel to the guard teeth 16 of the r clamping mem er 11, for the purpose of giving a fine shave. On reference to Figure 2, it will be apparent that the stud 14 in part will be received in the recess in the handle. and the end of the handle having this recess will be in contact with the rest or boss 17 of the clamping member 1'1, when the parts are assembledfor use.

On reference to Figure 3, it will be apparent that the clamping member 11 may be reversed, in which case the blade 12 will be in contact with the'rest or boss 17, and the upper end of the handle will be disposed in the recess 18 in contact with the clamping member 11. members 10 and 11 will be held in clamping engagement with the blade 12 which will not be flexed but will be gripped along the marginal edges thereof in a substantially flat conp purpose of clamping dition, thereby disposing the cutting edges of the blade in a changed relation with respect to the guard teeth 16, for the purpose of giving more pronounced cutting edges to suit a particular requirement of the user, as distinguished from the greater angular, disposition of the cutting edges shown in Figure 2 for a fine shave.

It will be apparent that the razor is adapt-- ed to present eight edges, gurxof one angularity and four-of another angularity.

In Figure 8 there is shown a' non-flexible blade 24 of quadrangular shape which presents four cutting edges. The blade 24 is rounded at the four corners and has the usual centering hole.

What is claimed is:

1. In a safety razor, the combination of cooperativeupper and Vlower blade clamping members, the upper member having a lower concaved face, and the lower member having an upper convexed face, said lower member being associable with the upper member so that the concaved face of the latter will oppose the convexed face of the former, for the therebetween a flexible lade in a iexed con ition to vary the angular dispositions of the cutting edges of the blade in relation to the edges of the clamping members" when they areassociated in the stated manner, and said lower member also being associable with the upper member so that the concaved face of the former will oppose the concaved face of the latter, said clamping members having co-operative means adapted for the purpose of clamping-therebetween an infiexible blade, to obtain a different angular disposition of the cutting edges of the blade in relation to the edges of the clamping mem- In this manner the clamping concaved face, and the lower member having an upper convexed face, said lower member being associable with the upper member so that the concaved face of the latter will o pose the convexed face of the former, for t e purpose of clamping therebetween a flexible blade in a flexed condition to Vary the angular dispositions of the cutting edges of the blade in relationtto the edges of the clamping members when they are associated in the stated manner, and said lower memberalso being associable with the upper member so that'tlie concaved face of the former will oppose the concaved face of theilatter, said clamping members having co-operative means adapted for the purpose of clamping therebetween an inflexible blade, to obtain a different angular disposition of-the cutting edges of the blade in relation to the edges of the clamping members when they are associated in the last stated manner, a handle, and engaging means on the handle and said clamping members to retain the latter 1n clamping engagement with the blade.

3. In a vsafety razor, the combination of cooperative blade clamping members consisting of an upper member and a separate lower member having guard portions on the edges thereof, each of said clamping members being concavo-convex in cross section,y said lower clamping member having a blade rest portion on its concaved face, a peg projecting from the concaved face of the upper clamping member, said lower clamping member being adapted to be arranged on said peg with its convexed face opposing the concaved face of the upper clamping member to co-operate with the upper clamping member, for the purpose of clamping a iexible blade therebetween in a flexed condition to var the angular dispositions of the cutting e ges of the blade with respect to said guard portions, and said lever clamping member also being adapted to be n,arranged on Y said peg with its concaved .face opposing the concaved face of the upper clamping member to co-operate with the latter for the purpose of clampin an inflexible blade therebetween to obtain a iierent angular disposition of the cutting edges of the blade with respect to said guard portions, a handle, and e 'gaging means on said peg and handle to retain the clamplin members in clamping engagement .with t e lade.
